The Kansas City Chiefs are rallying around long snapper James Winchester, whose father Michael was killed by a former Southwest Airlines employee outside of an Oklahoma City airport.

Chiefs coach Andy Reid said Wednesday that Winchester, who like his father played college football at Oklahoma, has returned to the state to be with his family.

Reid says he’s not sure if Winchester will be back for Sunday’s game against Tampa Bay.

Chiefs punter Dustin Colquitt says he spoke to Winchester, who told him: “Obviously this is a tough time for my family, but I appreciate the thoughts and prayers.”

Police say a former Southwest Airlines worker shot and killed Michael Winchester on Tuesday in retaliation for something that contributed to the attacker quitting his job with the airline last year. The attacker then killed himself.
